Jean Baptiste Vanmour, 1717
what to study here
It shows how a clear value hierarchy, a dark mass against pale figures, organizes a multi-figure portrait with soft edges and one precise carpet pattern.
Start with the value structure, because it carries the picture. The darkest darks are kept almost entirely in the left curtain, while the brightest lights gather on Lady Mary's face and neck and on Edward's white tunic. Squint and the curtain reads as one dark mass, the central group glows, and the landscape on the right drops to middle tones of tan and gold. Light comes from the upper left, so check that every shadow sits on the right side of its form. Notice the restraint in the faces. Lady Mary's face has slightly crisper but still gentle edges and is the most carefully rendered area; Edward's is paler and simpler. Edges elsewhere stay soft, especially in the loosely feathered trees. The geometric carpet is the one place with linear precision, and its tilted floor plane sets up the spatial stage. Copy the order the eye follows: face and neck, son, then carpet. Study how little modeling is needed once the value masses are right.
key decision
The painter confined the darkest darks almost entirely to the left curtain and concentrated the brightest lights on the faces and Edward's white tunic, so the figures glow against a dark anchor.
recreation guide
This artwork is a Baroque-era oil portrait by Jean Baptiste Vanmour, created in 1717. As a portrait, its primary intent is to represent specific human subjects—Lady Mary Wortley Montagu, her son Edward, and attendants—serving as a record of their appearance and status (Source 3). The work belongs to the tradition of Flemish Baroque painting, which often featured life-sized or monumental portraiture of nobility, influenced by artists like Rubens and Van Dyck (Source 6). The technique likely involves the complex layering methods characteristic of the 'old masters,' specifically the use of a monochrome underpainting (grisaille) followed by transparent glazes and semi-opaque scumbles to achieve depth and luminosity (Source 1).
estimated time
40-60 hours over 8-12 sessions (allowing for drying times between glaze layers)

materials
| item | purpose | modern equivalent |
|---|---|---|
| Oil paints (Ultramarine, White, Black, Red, Yellow earth tones) | Primary pigments for grisaille and glazing | Artist-grade oil paints |
| Linseed oil or Oil of Copavia | Medium for mixing paint and glazing; Source 1 specifically mentions oil of copavia for Reynolds' method, while general practice uses linseed (Source 7) | Stand oil or refined linseed oil |
| Mineral spirits or Turpentine | Thinner for initial layers and cleaning brushes (Source 7) | Odorless mineral spirits |
| Canvas | Support surface | Linen or cotton canvas |
| Charcoal or thinned paint | Initial sketching on the canvas (Source 7) | Vine charcoal or diluted oil paint |
| Varnish | Mixed with oil for later glazing stages to gain mastery (Source 1) | Dammar or synthetic resin varnish |
preparation
surface prep
The canvas should be primed with a ground suitable for oil painting. While specific priming details for Vanmour are not in the sources, traditional oil painting techniques of this period often involved a white or light-toned ground to facilitate the glazing process described in Source 1. Ensure the surface is smooth to allow for the fine finish expected in portraiture.
underdrawing
Begin by sketching the subjects onto the canvas using charcoal or thinned paint (Source 7). As this is a portrait intended to achieve a recognizable likeness (Source 3), the underdrawing must be precise in capturing the proportions and gestures of Lady Montagu, her son, and the attendants. Do not rely on stereotypes; if specific facial features are not described in the sources, focus on the general composition of a group portrait.
underpainting
Execute a grisaille (monochrome underpainting) using black, ultramarine, and white (Source 1). This step involves mentally extracting red and yellow colors to establish the tonal values of the composition (Source 1). This layer must be allowed to dry completely before proceeding. This technique is consistent with the practices of old masters who used glazing and scumbling (Source 1).

composition
The composition is a group portrait featuring Lady Mary Wortley Montagu, her son Edward, and attendants. While specific spatial arrangements are not detailed in the sources, Flemish Baroque portraiture often utilized life-sized or monumental scales for nobility (Source 6). The arrangement likely aims to harmonize the colors of the composition inherent to the nature of the objects (Source 2). Avoid inventing specific background details like wall hangings or furniture unless explicitly described, which they are not.
step by step
underdrawing
step 01
Sketch the figures of Lady Montagu, Edward, and attendants onto the canvas using charcoal or thinned paint.
Tip — Ensure accurate proportions for likeness (Source 3).
Initial sketching
underpainting
step 02
Paint a grisaille using black, ultramarine, and white. Mentally exclude red and yellow to focus on tonal values.
Tip — This layer must be completely dry before glazing (Source 1).
Grisaille
first pass
step 03
Apply transparent glazes of red and yellow tones over the dried grisaille. Use oil as a medium initially.
Tip — Glazing is a transparent coat of color (Source 1).
Glazing
refining
step 04
Use scumbling (semi-opaque painting) to adjust tones, particularly over darker grounds to create coldness or grey blooms.
Tip — The underlying painting should make itself felt through the scumble (Source 1).
Scumbling
step 05
Apply subsequent layers with varnish and oil mixed, once sufficient mastery is gained, to refine the color and luminosity.
Tip — Follow the 'fat over lean' rule to prevent cracking (Source 7).
Varnish glazing
finishing
step 06
Check for simultaneous contrast effects. Ensure that contiguous colors do not distort the perceived hue of adjacent areas.
Tip — Be aware that the eye may see complementary colors due to fatigue (Source 2).
Color harmony
critical techniques
Glazing and Scumbling
Glazing involves applying transparent coats of color, while scumbling uses semi-opaque paint over a darker ground. This method was practiced by old masters to achieve depth and luminosity (Source 1).
Fat over Lean
Each additional layer of paint should contain more oil than the layer below to ensure proper drying and prevent cracking (Source 7).
Simultaneous Contrast
Awareness that adjacent colors affect each other's appearance. The painter must account for this to accurately imitate the model's colors (Source 2).

what the eye sees
Light streams from the upper left, modeling Lady Mary Wortley Montagu's face and pale blue dress as the dominant luminous mass center-stage, with her son Edward in white beside her. A massive dark curtain on the left anchors the composition, while the landscape backdrop on the right opens into golden-hour tones—greens and browns suggesting depth beyond the interior space. Your eye lands first on Lady Mary's face and neck (the brightest, most carefully rendered area), then travels to her son, then settles on the warm geometric carpet beneath them. The floor plane is tilted toward the viewer, defining the spatial stage.
value structure
The value structure is highly legible: near-black darks in the curtain and deep shadows, pale ivory-cream in the figures (especially Edward's clothing and Lady Mary's face), warm mid-tones in the carpet and attendants' garments, and a middle-value landscape receding toward tan and gold. When squinting, the curtain on the left reads as a solid dark mass, the central figure group glows, and the landscape fades into atmospheric middle tones. The darkest darks are reserved almost entirely for the left curtain; the brightest lights concentrate on the faces and Edward's white tunic.

edges and brushwork
The edges are predominantly soft, especially in the background landscape where trees are suggested with loose, feathered strokes rather than defined forms. Lady Mary's face has slightly crisper but still gentle edges—this is refined portraiture, not tight rendering. The fabric of her dress flows with elegant, fluid strokes that suggest volume without obsessive detail; the folds are confident and loose. Only the geometric carpet pattern shows linear precision, grounding the composition. Overall, the brushwork recedes into smoothness, prioritizing luminosity and form over visible technique.
a working sequence
Establish the tonal underpainting
Block in the major value zones: very dark in the upper left curtain, light in the central figure area, warm mid-tones in the carpet, and middle tones fading into the landscape. Use burnt umber thinned with medium. This isn't about detail—it's about seeing the light, shadow, and half-tone zones as distinct masses. Pay attention to how the light rakes across from upper left, creating a shadow edge on the right side of Lady Mary's face and body.
Paint the background landscape
Block in the landscape recession with loose, horizontal strokes: golds and tans in the middle distance, greens in the foliage on the right, all receding in value and saturation. Keep this layer loose and soft—this is atmospheric perspective doing the work. Avoid dark details; let the distance be suggested by warmth and haze. The landscape should feel atmospheric, not photographic.
Establish the curtain mass
Paint the dark drapery on the left with bold, confident strokes using your darkest mix (ivory black + burnt umber). Let the folds suggest themselves through slight value variation rather than defined lines. This dark mass is your compositional anchor and sets the value key for everything else.
Block in the figures
Start with pale cream-ivory for Edward's white tunic and the upper portions of Lady Mary's blue dress overlay. Use titanium white with touches of yellow ochre and a whisper of blue (if available) for the pale luminous quality. Position the faces as slightly darker ovals—not detailed, just the head shape and basic features. Don't refine faces yet; focus on placement and value relationships.
Model the faces with restrained half-tones
Lady Mary's face is your most refined passage. Build the modeling using very subtle value shifts—don't jump from light to dark. Use burnt umber + white in the shadow side of her face and neck, keeping it warm and transparent rather than opaque. Edward's face should be paler and simpler. The key here is restraint: the faces are luminous and simple, not heavily modeled. Let the light do the work.
Render Lady Mary's dress and attendants
Her blue dress has a cream or pale yellow overlay—build this with pale yellows and whites, letting the underlying blue show through in shadows. The attendants wear warmer, earthier tones (reds, golds, ochres). Render the drapery with flowing, economical strokes—a few strokes suggest volume and fabric weight better than many tentative ones. Keep edges soft throughout.
Paint the decorative carpet
The foreground carpet has warm reds, golds, and geometric patterns. Block in the warm base color (red-ochre), then define the geometric design with darker lines. This is where you show precision—the pattern anchors the spatial depth. Use the geometric pattern to reinforce the floor plane's recession.
Unify and refine
Step back and check the overall value structure. The eye should move from the bright center (Lady Mary) outward. Soften any harsh edges between zones, especially where the figure meets the background. Add final touches: subtle highlights on faces (almost unmixed titanium white, sparingly applied), refine the landscape edges where needed. The whole should read as harmonious and calm, lit by golden light.
